摘要
本文在8根碳纤维布加固梁及2根对比混凝土梁受剪性能试验研究的基础上,分析了碳纤维布加固梁受剪性能及其影响因素,并在试验及主要影响因素分析研究的基础上采用统计方法建立碳纤维布加固梁受剪承载力的下限值计算公式。经统计分析后发现,该计算公式具有较高的精度,且由于采用承载力下限值方法建立,具有较高的安全度,可以较好地用于碳纤维布加固梁受剪承载力的计算。
The shear capacity of eight reinforced concrete beams with epoxy-bonded carbon fiber reinforced plastic （CFRP） sheets and two RC beams are experimentally investigated. The shear capacity and parameters inflecting the shear capacity of RC beams strengthened with externally bonded CFRP sheets are analyzed. A formula for the shear capacity based on statistical comparison is proposed. It is found that the calculated result is in a good agreement with that of the test.
